Abstract: In producing a sintered body comprising aluminum as its principal material and graphite as a lubricating additive through the steps of preparing a powder mixture of raw materials, compacting the powder mixture into a desired shape and sintering the compacted powder mixture, use is made of a graphite powder of which particles are coated with copper as the source of the entire quantity of graphite. Copper present on the surfaces of the graphite particles prevents graphite from adhering to aluminum particles and obstructing good sintering. At the stage of sintering, an eutectic reaction takes place between Cu and Al in the compacted powder mixture to form a liquid phase at a temperature below the. melting point of Al. Accordingly this method gives an accurately shaped sintered body with high physical strength. The powder mixture may additionally contain a limited amount of copper powder. To enhance abrasion resistance of the sintered body, preferably the powder mixture is made to contain an adequate amount of Si preferably together with a small amount of Mg.

Abstract: A structure, e.g. a temporary bridge, is erected on piles of adjusted height. The piles 9 used are hollow and have on their exteriors spiral propelling elements, e.g. a spiral blade 7, which, when the pile is driven rotatively under axial load, draws the pile into the ground. On reverse rotation still under axial load compaction occurs of the surrounding ground 12 and any added sand, stone orthe like 13 to assist in consolidating the ground, particularly if the ground is soft. The height of each pile is adjusted by a hollow adjuster 18 which is inserted into the open top of the pile and contains sand 17 which is discharged into a chamber 14 in the pile top to form a bed on which the adjuster 18 rests to determine the extent by which it projects from the pile and thus the effective pile height.

Abstract: Fuel injection is detected by listening for pulses of sound at or near 40 KHz from the region of the fuel injection and used to produce a first series of pulses representing the instants of fuel injection. A second series of pulses is derived from the first series and used to control a strobe lamp flashing on a rotating timing marker of the engine. The timing of the second series of pulses is adjusted until the strobe lamp flashes at the instants that the timing marker passes a stationary reference marker. The timing relationship between the first and second series of pulses then indicates the timing of the fuel injection.

Abstract: A method and apparatus for supplying a liquid medium, such as viscous printing ink, to the distributor and transfer rollers of printing machines. The apparatus includes an arcuate shaped distributor plate, an ink feed for dispensing a controlled quantity of liquid medium onto the distributor plate, and a feed roller that is mounted for cyclic movement in a path whereby it is rolled on the distributor plate to mix and uniformly spread the medium along the plate and about the periphery of the feed roller and then is moved into contact with the machine distributor roller to transfer the liquid medium thereto in a controlled manner. In one embodiment, the feed roller is moved in a cyclic circular path so that it first engages the distributor plate and then the distributor roller, and in another embodiment is moved in a reciprocating manner back and forth on the distributor plate and then engages the distributor roller. The ink feed is adapted to dispense controlled quantities of the liquid medium onto the distributor plate in timed relation with the cyclic feed roller movement.

Abstract: A process for preparing unsubstituted and alkyl substituted p-aminophenols. A charge mixture is prepared comprising an unsubstituted or alkyl substituted nitrobenzene, a highly dissociated acid, a catalyst containing platinum and a divalent sulfur compound in which sulfur is bonded to two other moieties, the sulfur compound being present in a proportion of from about 0.1 to about 100 moles per gram-atom of platinum. The mixture comprises an organic phase containing the substrate and an aqueous phase containing the acid. Hydrogen is introduced into the mixture at a pressure of 0-50 psig while the mixture is agitated at a temperature of 70-100°C, thereby causing the substrate to be reduced to phenylhydroxylamine or an alkyl substituted phenylhydroxylamine. The hydroxylamine is absorbed into the aqueous phase and therein rearranged to the substituted or unsubstituted p-aminophenol, which is recovered from the aqueous phase.

Abstract: A refuse packaging assembly of the kind comprising a refuse press having a pressing plunger which is axially movable in a pressing box, and a container which is adapted to be connected to the outlet end of the pressing box in order to be filled with refuse by the plunger, the container having a closure plug which is uncoupled from the container and coupled to the plunger for movement therewith when the container is connected to the press. The container carries at least one spring loaded pin which is biased into a coupling aperture in the closure plug to couple the two together, and the plunger carries at least one weaker spring loaded pin which aligns with the coupling aperture when the container is moved into position for connection to the press and the plunger is moved to a coupling position. A coupling lever which is operated by a power actuator to securely hold the container connected to the press simultaneously acts to retract the container pin from the coupling aperture, thereby uncoupling the plug from the container and allowing the plunger pin to move into the aperture to couple the plug to the plunger. Releasing the coupling lever automatically leads to uncoupling of the closure plug from the plunger and recoupling to the container.

Abstract: The permanent improvement in at least one property is achieved when the substrate absorbs a plurality of active chemical compounds which surround it. Each of these active chemical compounds is composed of one or more suitable active monomers of which each one is capable of entering a chemical bond with its like or a nonactive monomer. Each of the active monomers contains at least one active group which brings about the improved property without impairing the strength properties of the substrate. Some examples of improved properties are increased hydrophilicity, increased hydrophobicity, improved dyeability, improved soil repellence, improved colour fastness and increased antistatic properties. In a process for modifying such substrates, the substrate is treated with an adequate amount of a solution of the monomer(s) and the monomers are cured by irradiation or heating to form the active chemical compounds described. <IMAGE>

Abstract: A semiconductor laser diode structure operable at high power and brightness levels and having a relatively low threshold current, high efficiency, good mode stability, and reduced temperature sensitivity. One disclosed embodiments has twin parallel channels formed in a p type substrate, and employ an n type blocking layer to confine current to a region between and including the channels. The structure includes first and second inactive cladding layers, and an active layer forming a diode junction. The first or lower inactive layer is thinner in the region between the channels, and this results in a higher forward-bias voltage at the center of the active layer, thereby focusing the current near the central position. This current focusing mechanism, which is enhanced by the optional use of a curved active layer, results in the improved characteristics of the structure. By selecting the effective width of a contact stripe overlying the second or upper inactive layer, single or multiple optical gain filaments may be produced. Another disclosed embodiment has no blocking layer, but also employs twin channels to provide a desirable far-field distribution pattern.
